Description

L'invention concerne une trappe d'obturation de l'accès au bouchon de réservoir de carburant d'un véhicule automobile, conforme au préambule de la revendication 1.The invention relates to a shutter for closing the access to the fuel tank cap of a motor vehicle, in accordance with the preamble of claim 1.

De plus en plus fréquemment, sur les véhicules automobiles, la tubulure de remplissage du réservoir de carburant débouche dans une cuvette emboutie dans la carrosserie dudit véhicule automobile, cette extrémité débouchant de ladite tubulure de remplissage recevant, par ailleurs, un bouchon éventuellement verrouillable.More and more frequently, on motor vehicles, the filler neck of the fuel tank opens into a bowl pressed into the body of said motor vehicle, this end opening out of said filler neck receiving, moreover, a possibly lockable plug.

Par ailleurs, et pour des raisons, à la fois d'esthétique et de protection, la cuvette dans laquelle se situe, finalement, ce bouchon de remplissage du réservoir en carburant, vient à être refermée à l'aide d'une trappe d'obturation consistant en un portillon venant à coopérer, au travers de moyens d'articulation appropriés, avec une embase fixée à l'intérieur de ladite cuvette.Furthermore, and for reasons, both aesthetic and protective, the bowl in which is located, finally, this fuel tank filler cap, has just been closed using a trap door. obturation consisting of a gate coming to cooperate, through appropriate articulation means, with a base fixed inside said bowl.

En réalité et en dehors de ces moyens d'articulation, il est employé, très fréquemment, des moyens élastiques afin de relier le portillon à ladite embase et par conséquent à la carrosserie dudit véhicule automobile, de tels moyens élastiques maintenant ce portillon en position refermée tant qu'il n'y a pas d'intervention volontaire de la part de l'usager ou, au contraire, bloquant ce portillon en position ouverte, plus particulièrement, pendant l'approvisionnement du véhicule en carburant.In reality and apart from these articulation means, elastic means are used very frequently in order to connect the door to said base and therefore to the body of said motor vehicle, such elastic means keeping this door in the closed position. as long as there is no voluntary intervention on the part of the user or, on the contrary, blocking this gate in the open position, more particularly, during the supply of the vehicle with fuel.

Une telle obturation de l'accès au bouchon de réservoir de carburant d'un véhicule automobile est, notamment, connue par la demande de brevet en France n° 90.09413. En fait et dans ce mode de réalisation, il convient de noter que lesdits moyens d'articulation sont constitués, substantiellement, par deux oreilles disposées sur la face interne du portillon et comportant, chacune, un alésage se situant, précisément sur l'axe de rotation de ce portillon par rapport à l'embase rendue solidaire de la carrosserie du véhicule automobile. A noter, en outre, que cette embase est elle-même munie de deux plaques munies chacune d'un tourillon destiné, précisément, à s'insérer dans les alésages des oreilles équipant le portillon.Such closure of access to the fuel tank cap of a motor vehicle is, in particular, known from patent application in France No. 90.09413. In fact and in this embodiment, it should be noted that said articulation means consist, essentially, of two ears arranged on the internal face of the gate and each comprising a bore located precisely on the axis of rotation of this gate relative to the base made integral with the body of the motor vehicle. Note, moreover, that this base is itself provided with two plates each provided with a pin intended, precisely, to be inserted in the bores of the ears fitted to the gate.

De plus, les moyens élastiques garantissant le maintien du portillon soit, en position de fermeture de l'accès au réservoir, soit en position d'ouverture pour le remplissage en carburant, se présentent sous forme d'une lame élastique de forme approximative d'un "U" dont une aile vient à être rendue solidaire de la face interne du portillon, tandis que l'autre aile, qui lui est parallèle, présente une extrémité libre active destinée à coopérer avec des moyens d'action de l'embase selon trois plages de couples différentes en vue d'obtenir le fonctionnement désiré, à savoir, le maintien en position de fermeture de ce portillon et le blocage en position d'ouverture au-delà d'un passage d'un point dur.In addition, the elastic means ensuring the maintenance of the gate either in the closed position of the access to the tank, or in the open position for filling with fuel, are in the form of an elastic blade of approximate shape of a "U", one wing of which is made integral with the internal face of the gate, while the other wing, which is parallel to it, has an active free end intended to cooperate with means of action of the base according to three ranges of different torques in order to obtain the desired operation, namely, maintaining this gate in the closed position and locking it in the open position beyond a passage of a hard point.

Une trappe d'obturation reprenant les caractéristiques telles que décrites dans ce document antérieur, ne peut comporter qu'un portillon de forme rectangulaire ou approximativement rectangulaire, sachant que ce sont là les seules formes ou l'axe de rotation peut se présenter au plus près du bord vertical arrière de ce portillon, disposition qui est indispensable pour garantir le fonctionnement de cette trappe d'obturation.A shutter hatch incorporating the characteristics as described in this prior document, can only have a rectangular or approximately rectangular gate, knowing that these are the only forms where the axis of rotation can occur as closely as possible. the rear vertical edge of this gate, a provision which is essential to guarantee the functioning of this shutter.

En effet, il convient d'observer que dans le cadre de portillon de forme arrondie, l'axe de rotation de ce dernier, sur la carrosserie du véhicule automobile, est nécessairement déporté par rapport à son extrémité arrière. Aussi et lors de la rotation de ce portillon, cette extrémité arrière vient à plonger dans ladite carrosserie et, plus particulièrement, à l'intérieur de la cuvette recevant le bouchon de réservoir. Or, si cette extrémité arrière se situe à une distance quelque peu importante de cet axe de rotation du portillon, ce qui est, généralement le cas pour les portillons ronds, la profondeur de la cuvette est insuffisante pour autoriser une ouverture complète de la trappe d'obturation.Indeed, it should be observed that in the frame of a rounded gate, the axis of rotation of the latter, on the body of the motor vehicle, is necessarily offset relative to its rear end. Also and during the rotation of this door, this rear end comes to plunge into said bodywork and, more particularly, inside the bowl receiving the tank cap. However, if this rear end is located at a somewhat significant distance from this axis of rotation of the door, which is generally the case for round doors, the depth of the bowl is insufficient to allow complete opening of the hatch. shutter.

En quelque sorte et de manière à remédier aux inconvénients précités, il y a lieu, précisément, lors de cette rotation du portillon correspondant à la trappe d'obturation, de décaler son axe de rotation.In a way and in order to remedy the aforementioned drawbacks, it is necessary, precisely, during this rotation of the gate corresponding to the shutter hatch, to offset its axis of rotation.

Ceci fut notamment envisagé dans le cadre du document EP-A-0.124.410, qui décrit un mécanisme de trappe à essence pour véhicule automobile, ce mécanisme comprenant un portillon destiné à masquer, en position fermée, une portion emboutie dans la carrosserie pour recevoir un bouchon de réservoir. Ce portillon est articulé sur cette carrosserie au moyen d'un dispositif d'articulation à deux positions privilégiées correspondant aux positions fermées et ouvertes.This was in particular envisaged in the context of document EP-A-0.124.410, which describes a fuel filler mechanism for a motor vehicle, this mechanism comprising a flap intended to hide, in the closed position, a pressed portion in the body for receiving a tank cap. This gate is articulated on this bodywork at by means of an articulation device with two privileged positions corresponding to the closed and open positions.

En fait, ce dispositif d'articulation comprend un coulisseau dont une extrémité est montée articulée sur ledit portillon. Ce coulisseau se déplace, par ailleurs, à l'intérieur d'un fourreau de guidage venant à s'insérer, au travers d'une ouverture réalisée dans la portion emboutie, à l'intérieur de la carrosserie du véhicule, ce fourreau étant fixé dans cette portion emboutie au moyen d'une bride de fixation.In fact, this articulation device comprises a slide, one end of which is articulated on said door. This slide moves, moreover, inside a guide sleeve coming to be inserted, through an opening made in the stamped portion, inside the vehicle body, this sleeve being fixed. in this stamped portion by means of a fixing flange.

A noter, en outre, que dans le fourreau sont disposés des moyens de rappel élastique maintenus sous contraintes et tentant, de manière systématique, à ramener le coulisseau à l'intérieur de ce fourreau.Note, moreover, that in the sheath are arranged elastic return means maintained under stresses and attempting, systematically, to bring the slide back inside this sheath.

Finalement, ce dispositif d'articulation comprend deux paires de cames dont l'une est présente au niveau du portillon et vient à coopérer avec l'autre paire se situant à l'extrémité du coulisseau. Plus précisément, cette coopération des deux paires de cames, permet de garantir, lors de l'ouverture du portillon, une projection, vers l'extérieur et perpendiculairement au plan de la carrosserie, de l'axe de rotation de ce portillon. Cette projection assure, finalement, le dégagement de l'extrémité arrière de ce dernier de ladite carrosserie, ceci de manière à ne pas empêcher cette rotation ou à n'autoriser qu'une ouverture partielle dudit portillon.Finally, this articulation device comprises two pairs of cams, one of which is present at the gate and comes to cooperate with the other pair located at the end of the slide. More precisely, this cooperation of the two pairs of cams makes it possible to guarantee, when the door is opened, a projection, outwards and perpendicular to the plane of the bodywork, of the axis of rotation of this door. This projection ensures, finally, the release of the rear end of the latter from said body, this so as not to prevent this rotation or to allow only a partial opening of said door.

Bien que cette trappe d'obturation particulière, connue au travers du document EP-A-0.124.410, permet de satisfaire aux conditions exposées plus haut pour l'ouverture d'un portillon de forme ronde et, plus généralement, quelconque, il n'en reste pas moins qu'elle emploie un dispositif d'articulation fort complexe, faisant intervenir un nombre important de pièces nécessitant un temps de montage important sans compter qu'elles conduisent à un coût de fabrication élevé de cette trappe d'obturation. De plus, ce dispositif d'articulation présente, également, l'inconvénient d'être particulièrement encombrant. En effet, tel que déjà indiqué, le fourreau employé nécessite l'aménagement d'une ouverture dans la cuvette recevant le bouchon de réservoir, ouverture qui est, par ailleurs, gênante d'un point de vue des risques de corrosion auxquels elle conduit puisque c'est, généralement, au niveau des angles vifs de telles ouvertures qu'il y a amorçage de la rouille.Although this particular shutter hatch, known from document EP-A-0.124.410, makes it possible to satisfy the conditions set out above for the opening of a door of round shape and, more generally, of any type, 'the fact remains that it employs a very complex articulation device, involving a large number of parts requiring a significant assembly time besides that they lead to a high manufacturing cost of this shutter hatch. In addition, this articulation device also has the disadvantage of being particularly bulky. In fact, as already indicated, the sheath used requires the fitting of an opening in the bowl receiving the tank cap, an opening which is, moreover, troublesome from the point of view of the risks of corrosion. to which it leads since it is, generally, at the sharp angles of such openings that there is priming of the rust.

Il convient, également, de prendre en considération le fait, que la présence du fourreau empêche, généralement, le centrage de la bride dans le fond de la cuvette emboutie dans la carrosserie.It should also be taken into account that the presence of the sheath generally prevents the centering of the flange in the bottom of the bowl pressed into the body.

La présente invention se propose de remédier à l'ensemble des inconvénients précités et reconnus aux trappes d'obturation correspondant à l'état antérieur de la technique.The present invention proposes to remedy all of the aforementioned drawbacks recognized in shutter hatches corresponding to the prior art.

L'invention telle qu'elle est caractérisée dans les revendications, résout le problème et consiste en une trappe d'obturation de l'accès au bouchon de réservoir de carburant d'un véhicule automobile, comprenant un portillon relié, d'une part, au travers de moyens d'articulation et, d'autre part, par l'intermédiaire de moyens élastiques susceptibles de maintenir ledit portillon, soit en position de fermeture de la trappe, soit en position d'ouverture de cette dernière, à une embase solidaire de la carrosserie dudit véhicule automobile, lesdits moyens élastiques étant formés par une lame élastique présentant la configuration d'un "U" dont l'une des ailes parallèles est rendue solidaire de la face interne du portillon et dont l'autre aile parallèle présente une extrémité active coopérant avec des moyens d'action munissant ladite embase, lesdits moyens d'articulation comportant des moyens pour décaler, à la fois dans le plan de la carrosserie du véhicule automobile et suivant une direction perpendiculaire à cette dernière et de manière à s'en écarter, l'axe de rotation du portillon lors de l'ouverture de ce dernier, ces moyens étant constitués par la combinaison desdits moyens élastiques agissant sur les moyens d'action de ladite embase et par la coopération d'une paire de cames associées au portillon et d'une paire de rampes d'appui solidaires de cette embase.The invention as characterized in the claims, solves the problem and consists of a shutter closing the access to the fuel tank cap of a motor vehicle, comprising a wicket connected, on the one hand, through articulation means and, on the other hand, by means of elastic means capable of holding said door, either in the closed position of the hatch, or in the open position of the latter, to a fixed base of the bodywork of said motor vehicle, said elastic means being formed by an elastic blade having the configuration of a "U" of which one of the parallel wings is made integral with the internal face of the gate and of which the other parallel wing has a active end cooperating with action means providing said base, said articulation means comprising means for shifting, both in the plane of the body of the automobi vehicle the and in a direction perpendicular to the latter and so as to deviate therefrom, the axis of rotation of the gate when the latter is opened, these means being constituted by the combination of said elastic means acting on the means of action of said base and by the cooperation of a pair of cams associated with the gate and of a pair of support ramps integral with this base.

Les avantages obtenus grâce à cette invention consistent, essentiellement, en ce que l'on est en présence, au total, de trois pièces dont l'une s'identifie comme le portillon, l'autre l'embase et la troisième la lame élastique. En somme, on rejoint une simplicité de conception conduisant, non seulement à un coût de revient amoindri de la trappe d'obturation mais, surtout, à une fiabilité de fonctiomement accrue de cette dernière.The advantages obtained thanks to this invention consist, essentially, in that one is in the presence, in total, of three parts, one of which identifies as the gate, the other the base and the third the elastic blade . In short, we join a simplicity of design leading, not only to a reduced cost price of the hatch but, above all, to increased operating reliability of the latter.

On notera, par ailleurs, que les moyens d'articulation spécifiques à l'invention, bien qu'autorisant l'utilisation du portillon de forme indifférente, n'en présente pas moins un encombrement réduit ne nécessitant pas impérativement l'aménagement d'une ouverture quelconque dans la cuvette recevant le bouchon de réservoir, tel que ceci fut le cas pour certaines trappes d'obturation de l'état antérieur de la technique.It will be noted, moreover, that the articulation means specific to the invention, although allowing the use of the gate of indifferent shape, nevertheless have a reduced bulk that does not necessarily require the development of a any opening in the bowl receiving the tank cap, as was the case for certain shutter hatches of the prior art.

Tel que représenté sur ces dessins joints en annexe, la présente invention est relative à une trappe 1 d'obturation de l'accès au bouchon de réservoir de carburant (non représenté) d'un véhicule automobile.As shown in these accompanying drawings, the present invention relates to a hatch 1 for closing off access to the fuel tank cap (not shown) of a motor vehicle.

Plus particulièrement, il convient de rappeler que ce bouchon de réservoir vient à être appliqué sur l'extrémité d'une tubulure de remplissage en carburant, l'extrémité de cette tubulure venant à déboucher au niveau d'une cuvette 2 emboutie dans ladite carrosserie 3 du véhicule automobile.More particularly, it should be recalled that this tank cap comes to be applied to the end of a fuel filling pipe, the end of this pipe coming to open at a bowl 2 stamped in said bodywork 3 of the motor vehicle.

De manière à protéger l'accès à ce bouchon de réservoir et, par ailleurs, en vue d'améliorer l'esthétique de cette carrosserie 3 du véhicule automobile, ladite cuvette 2 dans laquelle débouche cette tubulure de remplissage est refermée au moyen de la trappe d'obturation 1.In order to protect access to this tank cap and, moreover, with a view to improving the aesthetics of this bodywork 3 of the motor vehicle, said bowl 2 into which this filling pipe opens out is closed by means of the hatch shutter 1.

En fait, cette dernière comporte un portillon 4 monté, grâce à des moyens d'articulation 5 ainsi que par l'intermédiaire de moyens élastiques 6, sur une embase 7 venant à être disposée à l'intérieur de la cuvette 2 et, donc, fixée à la carrosserie 3 du véhicule automobile.In fact, the latter comprises a door 4 mounted, by means of articulation means 5 as well as by means of elastic means 6, on a base 7 which comes to be disposed inside the bowl 2 and, therefore, attached to the body 3 of the motor vehicle.

De manière à faciliter la compréhension de la présente invention ainsi que son fonctionnement, il sera procédé, ci-dessous, à une description successive des trois pièces composant, en réalité, la trappe d'obturation 1, à savoir, le portillon 4, l'embase 7 et les moyens élastiques 6, sachant que les moyens d'articulation 5 sont en partie intégrés audit portillon 4 et à ladite embase 7.In order to facilitate the understanding of the present invention as well as its operation, there will be proceeded, below, a successive description of the three parts making up, in reality, the shutter hatch 1, namely, the gate 4, l base 7 and elastic means 6, knowing that the articulation means 5 are partly integrated into said door 4 and into said base 7.

Plus en avant de cette description, l'on précisera les intéractions existant entre chacune de ces pièces 4, 6 et 7.Further on in this description, the interactions existing between each of these parts 4, 6 and 7 will be specified.

Plus particulièrement et en ce qui concerne le portillon 4, tel qu'illustré dans les figures 1 à 4, 10 et 11, celui-ci comporte, au niveau de sa face interne 8, selon une disposition symétrique par rapport à un plan médian horizontal 9 et à proximité de son bord périphérique 10, deux cames 11, 12 se présentant sous forme d'ailes disposées perpendiculairement au plan dudit portillon 4, le profil de came étant déterminé par le chant 13 de ces ailes.More particularly and with regard to the gate 4, as illustrated in FIGS. 1 to 4, 10 and 11, the latter comprises, at the level of its internal face 8, in a symmetrical arrangement with respect to a horizontal median plane 9 and near its peripheral edge 10, two cams 11, 12 in the form of wings arranged perpendicular to the plane of said door 4, the cam profile being determined by the edge 13 of these wings.

Ces cames 11, 12 interviennent, plus particulièrement, dans le cadre de l'articulation du portillon 4 sur l'embase 7.These cams 11, 12 intervene, more particularly, within the framework of the articulation of the gate 4 on the base 7.

Par ailleurs, lesdites cames 11, 12 sont munies, d'une part, sur la face supérieure 14, respectivement sur la face inférieure 15, d'un tourillon 16, 17, intervenant, notamment, en tant que moyens de retenue de ce portillon 4 sur l'embase 7 lorsque la trappe est en position ouverte.Furthermore, said cams 11, 12 are provided, on the one hand, on the upper face 14, respectively on the lower face 15, with a pin 16, 17, acting, in particular, as means of retaining this gate 4 on the base 7 when the hatch is in the open position.

D'autre part, lesdites cames 11, 12 comportent, au niveau de la face inférieure 18, respectivement, la face supérieure 19, c'est-à-dire orientée en direction du plan médian horizontal 9, une oreille 20, 21 intervenant dans le guidage du portillon 4 lors de sa rotation sur l'embase 7.On the other hand, said cams 11, 12 comprise, at the level of the lower face 18, respectively, the upper face 19, that is to say oriented towards the horizontal median plane 9, one lug 20, 21 intervening in guiding the gate 4 during its rotation on the base 7.

Ces oreilles 20, 21 sont munies, en outre, et au niveau de leur partie arrière 22, de languettes 23, 24, ayant, en raison de leur coopération avec ladite embase 7, une fonction de retenue du portillon 4 à l'égard d'actions qui lui seraient imprimées verticalement lorsqu'il est en position de fermeture ou en position d'ouverture.These ears 20, 21 are further provided, and at their rear part 22, of tongues 23, 24, having, by reason of their cooperation with said base 7, a function of retaining the gate 4 with regard to actions that would be printed vertically when it is in the closed position or in the open position.

De plus ledit portillon 4 est pourvu, en outre, sur sa face interne 8 et au-delà des cames 11, 12 de rebords 25, 26 parallèles au plan médian horizontal 9 ayant pour fonction de guider et de positionner ce portillon 4 par rapport à la cuvette 2 lorsqu'on vient à refermer la trappe 1, ce positionnement étant obtenu au travers d'une coopération de ces rebords 25, 26 avec ladite embase 7.In addition, said gate 4 is provided, in addition, on its internal face 8 and beyond the cams 11, 12 with flanges 25, 26 parallel to the horizontal median plane 9 having the function of guiding and positioning this gate 4 relative to the bowl 2 when the hatch 1 is closed, this positioning being obtained through cooperation of these flanges 25, 26 with said base 7.

Par ailleurs, entre les cames 11, 12 et toujours selon une disposition symétrique par rapport au plan médian horizontal 9, le portillon 4 reçoit, sur sa face interne 8, deux glissières horizontales 27, 28 comportant, chacune, une rainure horizontale 29, 30 servant de logement à une partie des moyens élastiques 6. Ces rainures horizontales 29, 30 viennent à déboucher, au niveau du chant vertical avant 31, 32 desdites glissières horizontales 27, 28.Furthermore, between the cams 11, 12 and still in a symmetrical arrangement with respect to the horizontal median plane 9, the gate 4 receives, on its internal face 8, two horizontal slides 27, 28 each having a horizontal groove 29, 30 serving as a housing for part of the elastic means 6. These horizontal grooves 29, 30 come to open, at the front vertical edge 31, 32 of said horizontal slides 27, 28.

A l'avant de ces dernières, peuvent, en outre, être implantés des rebords de guidage 33, 34, d'une part, favorisant l'insertion de la partie concernée des moyens élastiques 6 à l'intérieur desdites glissières 28, 29 et, d'autre part, tout comme ces dernières, maintenant latéralement, ces moyens élastiques 6.At the front of the latter, can also be installed guide flanges 33, 34, on the one hand, favoring the insertion of the part concerned with elastic means 6 inside said slides 28, 29 and , on the other hand, just like the latter, now laterally, these elastic means 6.

Il est également prévu au niveau de cette face interne 8 du portillon 4 des moyens anti-recul 35 destinés à empêcher que les moyens élastiques 6 viennent à se dégager des glissières 27, 28 sans qu'il n'y ait une intervention volontaire de la part de l'usager.There is also provided at this internal face 8 of the door 4 anti-recoil means 35 intended to prevent the elastic means 6 from coming out of the slides 27, 28 without there being a voluntary intervention of the from the user.

Finalement, les glissières 27, 28 sont surmontées, dans leur partie arrière 36, d'un butoir 37 disposé perpendiculairement au plan médian horizontal 9 et constituant, tout comme les tourillons 16, 17, des moyens de retenue du portillon 4 sur l'embase 7, plus particulièrement, lorsque la trappe est amenée en position ouverte lors de l'approvisionnement du véhicule automobile en carburant.Finally, the slides 27, 28 are surmounted, in their rear part 36, by a stopper 37 disposed perpendicular to the horizontal median plane 9 and constituting, like the pins 16, 17, means for retaining the gate 4 on the base 7, more particularly, when the hatch is brought into the open position when the motor vehicle is supplied with fuel.

Quant à l'embase 7, illustrée dans les figures 5 à 7, 10 et 11, elle comporte une face inférieure 38 présentant, éventuellement, un bossage 39 destiné à s'insérer dans un logement prévu à cet effet dans le fond 40 de la cuvette 2 afin de garantir le positionnement, à l'intérieur de cette dernière, de cette embase 7. Celle-ci est, en fait, rendue solidaire de la carrosserie 3 du véhicule automobile au moyen d'organes de fixation, tel que vis et comporte, de ce fait, des orifices 41, 42 servant, précisément, de passage à ces organes de fixation.As for the base 7, illustrated in FIGS. 5 to 7, 10 and 11, it has a lower face 38 having, optionally, a boss 39 intended to be inserted in a housing provided for this purpose in the bottom 40 of the bowl 2 in order to guarantee the positioning, inside the latter, of this base 7. The latter is, in fact, made integral with the bodywork 3 of the motor vehicle by means of fixing members, such as screws and therefore comprises orifices 41, 42 serving, precisely, for passage to these fixing members.

Quant à la face supérieure 43, orientée en direction du portillon 4, de cette embase 7, elle présente, tout d'abord, deux rampes d'appui 44, 45 disposées symétriquement par rapport au plan médian vertical 46 de ladite embase 7, sur ces rampes d'appui 44, 45 venant à évoluer les cames 11, 12 correspondant au portillon 4, tel que ceci apparaîtra plus en avant dans la description.As for the upper face 43, oriented towards the gate 4, of this base 7, it has, first of all, two support ramps 44, 45 arranged symmetrically with respect to the vertical median plane 46 of said base 7, on these support ramps 44, 45 coming to evolve the cams 11, 12 corresponding to the gate 4, as this will appear further in the description.

Par ailleurs, lesdites rampes d'appui 44, 45 aboutent, à leur extrémité avant 47 à une paroi transversale 48 disposée perpendiculairement au plan de ladite embase 7.Furthermore, said support ramps 44, 45 end at their front end 47 at a transverse wall 48 arranged perpendicular to the plane of said base 7.

Cette paroi transversale 48 présente, au niveau de son bord supérieur 49 et au-delà des rampes d'appui 44, 45, c'est-à-dire dans une direction consistant à s'éloigner du plan médian vertical 46, des retours 50, 51 orientés en direction de la partie arrière 52 de l'embase 7 et disposés parallèlement à cette dernière. Ces retours 50, 51 sont destinés à s'enrouler en phase finale d'ouverture du portillon 4, autour des tourillons 16, 17 équipant ce dernier. Ainsi les retours 50, 51 viennent à compléter les moyens de retenue du portillon 4 sur l'embase 7 lorsque la trappe 1 est en position ouverte, moyens que constituent lesdits tourillons 16, 17.This transverse wall 48 has, at its upper edge 49 and beyond the support ramps 44, 45, that is to say in a direction consisting of moving away from the vertical median plane 46, returns 50 , 51 oriented towards the rear part 52 of the base 7 and arranged parallel to the latter. These returns 50, 51 are intended to be wound in the final phase of opening the door 4, around the pins 16, 17 equipping the latter. Thus the returns 50, 51 complete the means for retaining the door 4 on the base 7 when the hatch 1 is in the open position, means which constitute said pins 16, 17.

Cette paroi transversale 48 présente, en outre et sur sa face arrière 53, des encoches 54, 55 se situant de manière adjacente aux rampes d'appui 44, 45 et sur le côté de ces dernières orienté en direction du plan médian vertical 46. En fait, dans ces encoches 54, 55 viennent à s'insérer les oreilles 20, 21 équipant les cames 11, 12 du portillon 4 en vue d'assurer le guidage de ce dernier par rapport à ladite embase 7 au cours de sa rotation sur cette dernière.This transverse wall 48 has, in addition and on its rear face 53, notches 54, 55 lying adjacent to the support ramps 44, 45 and on the side of the latter oriented in the direction of the vertical median plane 46. In made, in these notches 54, 55 are inserted the ears 20, 21 fitted to the cams 11, 12 of the door 4 in order to ensure the guiding of the latter relative to said base 7 during its rotation on this last.

A noter qu'au droit de ces encoches 54, 55 mais disposés en bordure arrière 56 de l'embase 7, sont aménagés des encadrements 57, 58 dans lesquels s'insèrent les languettes 23, 24 équipant, à leur partie arrière 22, les oreilles 20, 21 ceci lorsque le portillon 4 vient à être refermé. Ces encadrements 57, 58 constituent, en combinaison avec lesdites languettes 23, 24, les moyens de retenue du portillon 4 contre d'éventuels agissements qui lui seraient imprimés dans une direction verticale, une fois refermé sur la cuvette 2.Note that at the right of these notches 54, 55 but arranged at the rear edge 56 of the base 7, frames 57, 58 are arranged in which the tongues 23, 24 are fitted, at their rear part 22, the ears 20, 21 this when the door 4 comes to be closed. These frames 57, 58 constitute, in combination with said tongues 23, 24, the means for retaining the door 4 against possible actions which would be printed to it in a vertical direction, once closed on the bowl 2.

Un autre retour 59 équipe, par ailleurs, la face arrière 53 et en bordure supérieure 49 de la paroi transversale 48. Ce retour 59 s'étend, également, parallèlement et en direction de la partie arrière 52 de l'embase 7. Toutefois, il vient à se situer dans le plan médian horizontal de cette dernière. La face inférieure 60 de ce retour 59 a pour but de coopérer avec le butoir 37 surmontant les glissières 27, 28 lorsque le portillon 4 est en position ouverte. Ainsi, la coopération de ce butoir 37 et du retour 59 permet, d'une part, de limiter l'angle d'ouverture du portillon 4 par rapport à l'embase 7 et, d'autre part, contrecarrer les actions susceptibles d'être exercées sur ce portillon 4 en vue de repousser celui-ci au-delà de sa position d'ouverture maximum, actions qui finalement pourraient avoir pour conséquence, l'arrachement de la trappe d'obturation 1.Another return 59 also equips the rear face 53 and the upper edge 49 of the transverse wall 48. This return 59 also extends parallel and in the direction of the rear part 52 of the base 7. However, it comes to lie in the horizontal median plane of the latter. The purpose of the lower face 60 of this return 59 is to cooperate with the stopper 37 surmounting the slides 27, 28 when the door 4 is in the open position. Thus, the cooperation of this stopper 37 and the return 59 makes it possible, on the one hand, to limit the opening angle of the gate 4 relative to the base 7 and, on the other hand, to counteract the actions liable to be exerted on this gate 4 in order to push it beyond its maximum opening position, actions which ultimately could have the consequence of tearing off the shutter hatch 1.

De plus, l'on remarquera la présence, sur cette embase 7, de moyens d'action 61 destinés à coopérer avec une extrémité active de l'autre partie non rendue solidaire du portillon 4, des moyens élastiques 6.In addition, it will be noted the presence, on this base 7, of action means 61 intended to cooperate with an active end of the other part not made integral with the door 4, elastic means 6.

En fait, ces moyens d'action 61 se présentent sous forme d'une came 61A dont le profil s'étend, au niveau de la face inférieure 38 de l'embase 7, depuis la partie arrière 52 de cette dernière jusqu'à sa partie avant 62, tout en remontant le long de la face avant 63 de la paroi transversale 48. Il convient de préciser, à ce propos, qu'un espace 64 persiste entre le bossage 39 et la face inférieure 38 de l'embase 7, ceci plus précisément, de sorte que les moyens élastiques 6 soient en mesure de coopérer avec ces moyens d'action 61 que constitue la came 61A.In fact, these means of action 61 are in the form of a cam 61A whose profile extends, at the level of the lower face 38 of the base 7, from the rear part 52 of the latter until its front part 62, while going up along the front face 63 of the transverse wall 48. It should be noted, in this connection, that a space 64 persists between the boss 39 and the lower face 38 of the base 7, this more precisely, so that the elastic means 6 are able to cooperate with these means of action 61 that constitutes the cam 61A.

De plus, on remarquera que les courbures 65, 66, 67 empruntées par ce profil de came, sont déterminées de telle sorte que lesdits moyens élastiques 6 viennent exercer une force de rappel sur le portillon 4, force dont le module et le sens viennent à varier au cours de la rotation dudit portillon 4.In addition, it will be noted that the curvatures 65, 66, 67 taken by this cam profile, are determined so that said elastic means 6 come to exert a restoring force on the door 4, a force whose modulus and direction come to vary during the rotation of said gate 4.

Ainsi, au travers de ce profil de came, les moyens élastiques 6 auront pour fonction, d'une part, de maintenir le portillon 4 refermé sur la cuvette 2 ou au contraire, d'assurer son blocage en position ouverte.Thus, through this cam profile, the elastic means 6 will have the function, on the one hand, of keeping the door 4 closed on the bowl 2 or, on the contrary, of ensuring its blocking in the open position.

Ainsi, la première courbure 65, s'étendant depuis la partie arrière 52 de l'embase 7 jusqu'à sa partie avant 62, est déterminée de sorte que l'action des moyens élastiques 6 vienne à garantir le rappel du portillon 4 en position de fermeture. Par contre et au-delà de cette première courbure 65, le profil de la came 61A comporte une seconde courbure 66 remontant le long de la face avant 63 de la paroi transversale 48. Au niveau de cette seconde courbure 66, les moyens élastiques 6 rencontrent un point dur au-delà duquel leur action sur le portillon 4 vient à se modifier puisque ce dernier est, alors, rappelé en position d'ouverture.Thus, the first curvature 65, extending from the rear part 52 of the base 7 to its front part 62, is determined so that the action of the elastic means 6 comes to guarantee the return of the gate 4 in position closing. By cons and beyond this first curvature 65, the profile of the cam 61A comprises a second curvature 66 rising along the front face 63 of the transverse wall 48. At the level of this second curvature 66, the elastic means 6 meet a hard point beyond which their action on the gate 4 comes to change since the latter is then recalled to the open position.

Puis l'on distingue une troisième courbure 67, se situant en bout de ce profil de came 61A et qui, contrairement aux courbures 65, 66 précédentes est de forme concave et délimitée, finalement, par un rebord 68 se situant en bordure supérieure 69 de la face avant 63 correspondant à ladite paroi transversale 48.Then there is a third curvature 67, located at the end of this cam profile 61A and which, unlike the previous curvatures 65, 66 is of concave shape and delimited, finally, by a rim 68 located at the upper edge 69 of the front face 63 corresponding to said transverse wall 48.

En fait et au travers de cette troisième courbure 67 du profil de came 61A, les moyens élastiques 6 viennent à garantir le blocage dudit portillon 4 en position ouverte notamment pendant l'approvisionnement en carburant du véhicule automobile.In fact and through this third curvature 67 of the cam profile 61A, the elastic means 6 come to guarantee the locking of said door 4 in the open position in particular during the supply of fuel to the motor vehicle.

Quant à ces moyens élastiques 6, illustrés dans les figures 8 à 11, ceux-ci sont constitués par une lame élastique d'une certaine hauteur 70 empruntant la forme approximative d'un "U" de manière à définir deux ailes parallèles 71, 72.As for these elastic means 6, illustrated in Figures 8 to 11, these consist of an elastic blade of a certain height 70 taking the approximate shape of a "U" so as to define two parallel wings 71, 72 .

L'une de ces ailes parallèles 71 est rendue solidaire de la face interne 8 du portillon 4.One of these parallel wings 71 is made integral with the internal face 8 of the door 4.

Plus précisément, l'extrémité libre 73 de cette aile 71 est engagée dans les rainures 29, 30 des glissières 27, 28 jusqu'à la hauteur d'épaulements 74, 75 définie au travers de décrochements 76, 77 pratiqués dans le chant supérieur 78 et inférieur 79 de cette aile 71.More specifically, the free end 73 of this wing 71 is engaged in the grooves 29, 30 of the slides 27, 28 up to the height of shoulders 74, 75 defined through recesses 76, 77 made in the upper edge 78 and lower 79 of this wing 71.

Une découpe en forme de "U" 80 est, par ailleurs, pratiquée dans la partie avant 81 de cette aile 71, de manière à définir une lame 82 dont le chant avant 83 est en mesure de coopérer avec les moyens anti-recul 35 équipant la face interne 8 du portillon 4 pour, précisément, empêcher que les moyens élastiques 6 et, plus particulièrement, l'aile parallèle 71 ne viennent à se dégager de ces glissières 27, 28.A "U" shaped cutout 80 is also made in the front part 81 of this wing 71, so as to define a blade 82 whose front edge 83 is able to cooperate with the anti-recoil means 35 fitted the internal face 8 of the door 4 to, specifically, prevent the elastic means 6 and, more particularly, the parallel wing 71 from coming out of these slides 27, 28.

Tandis que l'autre aile parallèle 72 comporte une extrémité active 84 destinée à coopérer avec les moyens d'action 61 que constitue la came 61A.While the other parallel wing 72 has an active end 84 intended to cooperate with the action means 61 that constitutes the cam 61A.

En fait, cette extrémité active 84 est repliée en forme d'un "S" en direction de la première aile parallèle 71 de manière à définir un bossage inférieur 85 limitant le contact avec le profil de la came 61A à une génératrice.In fact, this active end 84 is folded in the shape of an "S" in the direction of the first parallel wing 71 so as to define a boss lower 85 limiting contact with the profile of cam 61A to a generator.

Ainsi et partant de la position de fermeture de la trappe 1, pour atteindre la position d'ouverture par rotation du portillon 4, cette extrémité active 84 vient à coopérer avec la première courbure 65 du profil de la came 61A. Au cours de cette coopération, lesdits moyens élastiques 6 exercent, sans cesse, une force de rappel sur le portillon 4 en direction de fermeture. Puis, tout en insistant dans le sens d'ouverture dudit portillon 4, ladite extrémité active 84 évolue le long de la seconde courbure 66 du profil de ladite came 61A, progression au cours de laquelle l'action desdits moyens élastiques 6 vient à se modifier de manière à exercer une force de rappel sur ce portillon 4 dans sa direction d'ouverture.Thus and starting from the closed position of the hatch 1, to reach the open position by rotation of the door 4, this active end 84 comes to cooperate with the first curvature 65 of the profile of the cam 61A. During this cooperation, said elastic means 6 constantly exert a restoring force on the door 4 in the closing direction. Then, while insisting in the direction of opening of said gate 4, said active end 84 evolves along the second curvature 66 of the profile of said cam 61A, progression during which the action of said elastic means 6 changes so as to exert a restoring force on this door 4 in its opening direction.

Finalement, cette extrémité active 84 et, plus particulièrement le bossage inférieur 85 de sa structure en forme de "S", viennent à se loger dans la forme concave que définit la troisième courbure 67 du profil de cette came 61A. A noter, à ce propos, que le rebord 68 vient à servir de butée à cette extrémité active 84 des moyens élastiques 6 de sorte que ceux-ci ne s'échappent inopinément des moyens d'action 61 correspondant à l'embase 7. L'on remarquera, par ailleurs, qu'à l'approche de cette extrémité active 84 de l'aile parallèle 72 correspondant aux moyens élastiques 6, est aménagée une lumière 86 dans laquelle vient à s'insérer un ergot 87 équipant le chant avant 88 dudit rebord 68, configuration qui ne constitue qu'une sécurité additionnelle à l'éventualité exposée au préalable, à savoir, l'échappement de l'extrémité active 84, correspondant à ces moyens élastiques 6, des moyens d'action 61 de l'embase 7.Finally, this active end 84 and, more particularly the lower boss 85 of its "S" shaped structure, come to be housed in the concave shape that defines the third curvature 67 of the profile of this cam 61A. Note, in this regard, that the rim 68 comes to serve as a stop at this active end 84 of the elastic means 6 so that they do not unexpectedly escape from the action means 61 corresponding to the base 7. L ', it will be noted, moreover, that when approaching this active end 84 of the parallel wing 72 corresponding to the elastic means 6, a light 86 is arranged in which a lug 87 is fitted fitting the front edge 88 of said rim 68, a configuration which constitutes only additional security to the eventuality previously exposed, namely, the escape of the active end 84, corresponding to these elastic means 6, means of action 61 of the base 7.

Les figures 10 et 11 illustrent plus particulièrement le fonctionnement de la trappe d'obturation 1 conforme à l'invention.Figures 10 and 11 illustrate more particularly the operation of the shutter hatch 1 according to the invention.

On y observe, à ce propos, la coopération des cames 11, 12, correspondant au portillon 4, avec les rampes d'appui 44, 45 équipant l'embase 7 et qui, en combinaison avec les agissements des moyens élastiques 6 sur les moyens d'action 61 de cette embase 7 constituent, avantageusement, des moyens 89 pour décaler à la fois dans le plan 90 de la carrosserie 3 et suivant une direction perpendiculaire 90A à cette dernière de manière à s'en écarter, l'axe de rotation du portillon 4 lors de l'ouverture de ce dernier. En quelque sorte, ce portillon 4 peut, au travers de ces moyens de décalage 89, équipant les moyens d'articulation 5 que constitue la combinaison dudit portillon 4, de l'embase 7 et des moyens élastiques 6 comporter n'importe quelle forme et, notamment, il peut être rond sans que son extrémité arrière 91, se situant, sans cesse au-delà dudit axe de rotation ne vienne à gêner l'ouverture du portillon 4 en prenant appui, soit sur la carrosserie 3 ou encore sur le fond de la cuvette 2.We observe, in this regard, the cooperation of the cams 11, 12, corresponding to the gate 4, with the support ramps 44, 45 fitted to the base 7 and which, in combination with the actions of the elastic means 6 on the means of action 61 of this base 7 advantageously constitute means 89 for shifting both in the plane 90 of the body 3 and in a direction perpendicular 90A to this last so as to deviate therefrom, the axis of rotation of the gate 4 when the latter is opened. In a way, this gate 4 can, through these offset means 89, equipping the articulation means 5 that constitutes the combination of said gate 4, of the base 7 and of the elastic means 6 have any shape and , in particular, it can be round without its rear end 91, lying, constantly beyond said axis of rotation, interfering with the opening of the door 4 by resting either on the body 3 or on the bottom of the bowl 2.

On notera, en outre, que tant au travers des moyens de retenue que constitue la coopération des tourillons 16, 17, équipant le portillon 4, avec les retours 50, 51 de la paroi transversale 48 correspondant à l'embase 7, ainsi qu'aux moyens de retenue que forment les languettes 23, 24 destinées à s'insérer dans les encadrements 57, 58 et, plus particulièrement, les moyens de guidage formés, d'une part, par la coopération des oreilles 20, 21 avec les encoches 54, 55 de ladite paroi transversale 48 et, d'autre part, par les rebords 25, 26 en combinaison avec les chants supérieur 92 et inférieur 93, toujours, de cette paroi transversale 48, on préserve la tenue mécanique de la trappe d'obturation 1 de toute action qui lui serait imprimée lorsque le portillon 4 est, respectivement, en position d'ouverture, en position de fermeture ou, enrore, dans une disposition intermédiaire.It will also be noted that both through the retaining means constituted by the cooperation of the pins 16, 17, equipping the gate 4, with the returns 50, 51 of the transverse wall 48 corresponding to the base 7, as well as the retaining means formed by the tongues 23, 24 intended to be inserted in the frames 57, 58 and, more particularly, the guide means formed, on the one hand, by the cooperation of the ears 20, 21 with the notches 54 , 55 of said transverse wall 48 and, on the other hand, by the flanges 25, 26 in combination with the upper 92 and lower 93 edges, always, of this transverse wall 48, the mechanical strength of the shutter hatch is preserved. 1 of any action which would be printed to it when the gate 4 is, respectively, in the open position, in the closed position or, furthermore, in an intermediate arrangement.

Il convient d'observer, en outre, qu'en dehors des sécurités existantes pour éviter que les moyens élastiques 6 et notamment leur extrémité active 84 ne vienne à quitter les moyens d'action 61 de l'embase 7, les moyens de retenue formés par le retour 59 équipant la face arrière 53 de la paroi transversale 48 et le butoir 37, jouent un rôle tout particulier sur le plan de cette tenue mécanique de la trappe d'obturation 1 lorsque l'on tente à conférer au portillon 4 une rotation complémentaire alors que celui-ci a atteint sa position d'ouverture maximum.It should also be observed that, apart from the existing safety devices to prevent the elastic means 6 and in particular their active end 84 from coming from the action means 61 of the base 7, the retaining means formed by the return 59 fitted to the rear face 53 of the transverse wall 48 and the stopper 37, play a very special role in terms of this mechanical strength of the shutter hatch 1 when an attempt is made to give the gate 4 a rotation while it has reached its maximum opening position.

On remarquera également, qu'en ce qui concerne le profil des cames 11, 12, et celui des rampes d'appui 44, 45, ils sont choisis de manière à obtenir l'amplitude du décalage désiré en ce qui concerne l'axe de rotation du portillon 4, ceci dans le plan 90 de la carrosserie 3 ainsi que dans la direction 90A qui lui est perpendiculaire et de manière à s'en écarter.It will also be noted that, with regard to the profile of the cams 11, 12, and that of the support ramps 44, 45, they are chosen so as to obtain the amplitude of the desired offset as regards the axis of rotation of the gate 4, this in the plane 90 of the body 3 as well only in the direction 90A which is perpendicular thereto and so as to deviate therefrom.

Toutefois, il peut être avantageux que les rampes 44, 45 présentent au niveau de leurs extrémités avant 47 et arrière 94 un profil correspondant, précisément, à celui des cames 11, 12 de sorte que, lorsque celles-ci viennent à atteindre, ces extrémités 47, 94 des rampes d'appui 44, 45, l'on obtienne un effet de butée limitant, en dehors des actions assurées par les différents moyens de retenue précités, ce décalage de l'axe de rotation dudit portillon 4 sur l'embase 7.However, it may be advantageous for the ramps 44, 45 to have at their front 47 and rear 94 ends a profile corresponding precisely to that of the cams 11, 12 so that, when these come to reach, these ends 47, 94 of the support ramps 44, 45, an abutment effect is obtained limiting, apart from the actions provided by the various aforementioned retaining means, this offset from the axis of rotation of said gate 4 on the base 7.

En conclusion, la présente invention est particulièrement intéressante en ce qu'elle conduit à une trappe d'obturation 1 constituée, en tout et pour tout, de trois pièces, à savoir un portillon, des moyens élastiques et une embase tout en autorisant, au travers de la coopération de ces trois pièces, le décalage dudit portillon par rapport à la carrosserie du véhicule automobile dans une double direction, à savoir, parallèlement au plan de cette carrosserie et perpendiculairement à cette dernière de sorte que, finalement, ce portillon peut être de forme quelconque et notamment, ronde sans que l'on rencontre de problème au fonctionnement, tel que ceci fut notamment le cas pour les trappes connues dans l'état antérieur de la technique.In conclusion, the present invention is particularly advantageous in that it leads to a shutter hatch 1 consisting, in all and for all, of three parts, namely a gate, elastic means and a base while allowing, at through the cooperation of these three parts, the offset of said gate relative to the body of the motor vehicle in a double direction, namely, parallel to the plane of this body and perpendicular to the latter so that, ultimately, this gate can be of any shape and in particular, round without encountering any problem in operation, as this was particularly the case for the hatches known in the prior art.
